How to get the same value from the input "xfield[2][h2]"?

Question

PHP

Need help with array processing.

There are several inputs:

<input id="xf_txt1" name="xfield[1]" value="Заголовок1" class="head_txt"/>
<input id="xf_txt2" name="xfield[2][h2]" value="Заголовок2" class="head_txt"/>
<input id="xf_txt3" name="xfield[3]" value="Заголовок3" class="head_txt"/>

php itself:

foreach( $_POST['xfield'] as $item ) {
 $items[] = $item;
}

$add = implode( $items,'<br>' );

Outputs:

Заголовок1
Array
Заголовок3

Answer 1

options:
1. remove [h2] from the input
2. learn how to work with arrays in general and is_array in particular
3. forget to bypass the array, work directly with indices.
4. think of other ways
